Missing Emails Outlook - Not all my emails come through

Question

Missing Emails Outlook - Not all my emails come through

Kim Tews 25

I get some of my emails but not all. I've had people send me text emails and some come through others don't. Personal and business emails are missing.

I only am using 26% of my storage.

I cleared my history.

I don't have any filters or rules within my outlook

I checked junk/spam and clutter and archive but they are not there

It doesn't appear to be a server issue

I'm not forwarded to another account.

What can I do.

Dear @Kim Tews

Thank you so much for contacting Microsoft Q&A Support.

I really understand that you are facing the inconvenience that some of your emails are missing. Also, I appreciate that you have tried many workarounds; however, it still does not work. Therefore, please kindly see this article and try it first: Email is missing from your Outlook.com inbox - Microsoft Support

Besides that, I find several suggestions that may help you, please consider trying them:

1.If you're managing their email domain (e.g., via Microsoft 365 or another provider), check the message trace or email logs to see if the missing emails were rejected or delayed. User's image

References: Run a message trace and view the results in the Exchange admin center in Exchange Online | Microsoft Learn

2.If you use Outlook desktop or mobile:

Try accessing Outlook Web to see if emails appear there.
Check if any add-ins are interfering.
Ensure you are syncing properly (check for sync errors if applicable).

3.You should check Blocked Senders or Safe Senders because sometimes senders are unintentionally blocked:

Go to Settings > Mail > Junk email in Outlook.
Check Blocked senders and Safe senders lists.

4.You should check the quarantine portal or security dashboard because even if spam/junk folders were checked, some emails might be quarantined by Microsoft Defender for Office 365.

You can consult in here: Find and release quarantined messages as a user - Microsoft Defender for Office 365 | Microsoft Learn

User's image Additionally, you should use tool to check your MX records which are correctly configured. And even if Outlook rules are clear, please kindly check for the Transport rules in Microsoft 365 Exchange Admin Center. Mail flow rules that might redirect or delete emails.

Wish you a pleasant day!

I previously reviewed all the steps listed on https://support.microsoft.com/en-us/office/email-is-missing-from-your-outlook-com-inbox-c70b4a9a-caa5-4e8c-a88a-3372215af25e

I don't have the functionality to do a message trace or mail flow.

I checked the Outlook app on my phone is consistent with what I see when I access Outlook via a browser window

I checked Check Blocked senders and Safe senders list and it's "standard" and I reviewed the addresses in my block sender

I'm honestly not sure if it worked. I am receiving some emails but have not found a few that were send previously that never came through.

The information you provided was helpful and I'm hoping maybe after all this work, it will solve the problem moving forward.

For example, one email that was sent to me and never came through had a Micro shared excel sheet. When the person sent the same email to my work email address, it came through fine.

Dear @Kim Tews

Good day! Thank you so much for your response to Microsoft Q&A Forum.

Based on your new information, the reason may not only come from your side, but the sender settings may affect it. You can also ask them to add your email address to Safe Senders List Properly to ensure you are added to the Safe Senders list in their Outlook settings, not just in contact. Besides that, you mentioned that it had problem with email contained attachments. Therefore, I recommend you can ask the senders to check on their side about the transport rules in Exchange Admin Center and the inbox rules of Outlook as well. This is to ensure that they do not have any rules that prevent them from sending emails with attachments.

I really appreciate that you have tried all of my suggestions.

Wish you all the best!
